Does anyone knows why the engine sound of our car gets very low when other cars are near? This happens mainly when leaving the pits full of opponent cars and on race starts. On race starts this situation makes the starting a lot more difficult as we cannot perceive well our engine rotation. Anyone knows if there's a way to control this?
Thanks a lot.
Pedro

Sorry no answer but have been aware of this issue in the past.
Hopefully someone will respond who has better memory.

Was it something real simple like reduce sounds to 4?

Still thinking...

John, reducing the number of sounds in the Options menu helps a litlle bit, but not enough to keep the volume of our engine steady. It doesn't drop so much but it still drops when the other cars are near.

Bruce, my OS is Win7, and yes, I don't remember too to have this problem 15 years ago with older operating systems...

I'm having the same issue in Win7, no solution sadly.

I so well recall an online race with the ADC at Salzburg '74 many years ago when, from pole position, when I joined the grid, I could only just hear my Weslake above the sound of other cars on the grid.  My wav file was being drowned out by the other engine notes.  I ran off at the first hairpin being completely overwhelmed by the other sounds.  Ever since, I've used tuned wav volumes with 100% assigned to my ride and 50-70% to others.  I lot of work to achieve but worth it.

changing the other cars to 50-70% ?  is that done with a sound edit program, for each wav file?
its not 'in game' is it?

Have to use a 3rd party sound editor.
Used this one in the past, Audacity, (link to SourceForge btw), to raise driver engine sound rather than lower others.

But, is this the fix or a bandaid?

bandaid...i like to try / test different cars.  so this adjustment would need be done every time i choose to race a different machine - and - if i change the Ferrari to louder, won't that affect ALL the other Ferrari's on track as well?

Right, every chassis uses the same sound file after all.

Is it possible that this has to do with the installer having set the sounds default to mono?

Never occurred to me on Win10.
If I could try and draw and hypotesis, I'd say that the cause might be the sounds being in mono: the buffer is able to reproduce all the sounds clearly, but the cones of your headset / your speakers are overloaded and mix everything in a huge blob of sound. Sometimes it happens when the sounds are in mono... try stereo sounds and all the sounds possible in the menu. If that happens again, try with another pair of speakers/headphones.

IIRC several tests were done long time ago regarding this topic.
For what I recall the best results were when all sounds being in mono; is then the system that make them heard at the left or the right depending on the position of the car.
If the other car is on your left, you will hear the sound on your left ear but the sound itself that the car output is a mono emission.

This is a guess, not sure about it but I think Wolfgang mentioned it once; if you have some mono and some other stereo then problems arise.

I think we had this conversation before too Gino.
In real life the car in front of you on the grid, blowing it's exhaust in your face, would be louder than your own car blowing it's exhaust well behind you.
Of course you have your earplugs in and a helmet on too, don't you?
It's very important to do some practice starts to the first turn because it's seldom the same as a lap under way.

I think this is true.  GPL's sound system places the sounds at specific directions and distances from the player's head.  Your PC's sound system then tries to replicate that 3D positioning as best as it can.  In theory, multiple speakers situated around the player's head should work better than using only two speakers in front for example.

Because of this, mono sounds should be better than stereo and mixing the two is probably not a good idea.

Friends, I think we solved this problem:

In GPL "Options", reducing the volume to about 25% instead of having it at 100%, solves the problem. At least, in my installation.

Let me know those of you that have the same problem if this solves in your installations too.

Thank you all once again for your support.

Pedro, I did not think to mention what you have found out.  I have always set my in-game Sound Volume to 50%.  Then, I adjust what I hear by setting my speaker volume to the level that fits the time-of-day.  :)

Thanks for making this clear to the community.

Greg, my sound volume was previously at 100%. Don't make sense to me that lowering the general volume could change the relation between the volume of the various sounds, but in fact thats what happened.
